    The capacity tester is easy to operate. On the left side of the battery compartment the power supply comes with a 18650 cell or alternatively the tester can be operated with a 12V power supply. On the pictures the result is the right 18650 cell. 1342 shows the mAh and 4868 shows the mWh. The 18650 was tested with another device, which is noted on the cell with 1548 mAh.

    It is interesting capacity Liion 18650 cells tester. One side is for powering ekectronics circuits and the other is for testing capacity. It works fine showing both the capacity in mAh or in mWh. The controll is a bit confuse but I used for it. It is cheap but reliable. I rather move the discharging resistor far awy from the cell because of intensive heat production by the testing. Usable product for DIY makers.

    Good tester, I just set the voltage to 3.2Volt. At 3.5V, the battery reached the prescribed capacity. Otherwise, there is no need to worry about the destruction of the printed circuit boards by hot resistance. There is a maximum loss of 2W. I insert a small Teflon plate between the battery and the resistor.

    The package arrived 9 days after ordering. The product is quite well and simply processed, it works as it should. The only thing I can criticize is that there was no user manual in the package, but you can simply translate the Chinese on Google translator. The device heats up to about 80°C during discharge. For me, a good product for the money.

    I like it, it’s good for the price. I wish it had English silk screen instead and moved the resistor away from the cell. I made a heat shield put of copper tape and I also moved the resistor up and further away as it produces quite a bit of heat.

    Comes sealed in electrostatic bag. The module displays multiple electronic parameters, including Voltage, Consumed Power and Battery Capacity. It does everything it advertises. You can use a 2pin power cable with a 12V wall adapter to power the module. My only complaint is that both 18650 battery holders are too tight. So it is not compatible with protected or button top 18650 cells.
